Abstract (en)
[origin: WO02084232A1] A control for a continuously moving weighing conveyor first triggers on a predetermined sensed weight (104). The control determines a first inflection point on the weight waveform defined as the "maximum positive slope" (106). Then the control begins recording weight samples at a sampling rate. The control checks the weight waveform of sampled weights for a slope which is a first pre-selected percentage of the maximum slope but negative in slope value "weight-off-scale" point (110). The control then looks backward through the recorded data of weight samples to find another point which has a slope which is a second preselected negative percentage of the maximum positive slope "end sample position"(114). Then a "start sample position" (118) is determined to fall within, or at the start of, a flat region of the waveform. The values within the sample period are then averaged to determine a static weight.
